scout: add German DSGVO text patterns + Usercentrics shadow DOM support

- German accept texts: Alle akzeptieren, Akzeptieren, Zustimmen, Einverstanden, etc.
- Usercentrics (shadow DOM) support — very common with German publishers
  (Bild, Spiegel, Focus, etc.) — requires shadowRoot traversal, not addressable
  by normal CSS selectors
- Consentmanager selectors — another common German CMP
- Note: German sites tested (Spiegel, Zeit, finanzen.net, Bild) showed no banners
  because Pydoll reuses the existing Chrome user profile with stored consents.
  New-site behaviour will be handled by the added patterns.
